While the palace said the queen would continue to carry out “light, desk-based duties” and could conduct meetings via Zoom, she will not take part in any official events or ceremonies, including the Festival of Remembrance, a gala scheduled for Nov.
For the queen, 95, to cancel her participation in an event two weeks in advance attests to the extraordinary precautions her medical team is taking.
Last week, the queen spent one night in a hospital in London for what the palace said were preliminary tests.
Buckingham Palace did not offer any new details about the queen’s condition, beyond saying she remained in good spirits and had recorded a video address to be broadcast at the opening of the climate conference.
Aides said last week that the queen’s decision to cancel the Northern Ireland trip was not related to Covid-19.
People with ties to the palace suggested that the decision to cancel her appearances was motivated by a desire to give certainty to the organizers of events like the Festival of Remembrance.
The queen had surprised some royal observers by resuming a hectic public schedule following the death in April of her husband, Prince Philip.
Recent images of the queen have showed her generally alert and smiling, though she was photographed using a walking stick at a ceremony in Westminster Abbey.
After more than a year behind closed doors, aides said there was pent-up demand for the queen to appear in public.
